.To preview a QuickTime movie:1 Add the number of frames to the Timeline that correspond to the length of theQuickTime movie you want to play.2 Choose Control > Play.Note: You cannot preview QuickTime movie content using the Control > Test Moviecommand.To set the directory path of a QuickTime movie file:1 Choose Window > Library and select the QuickTime movie you want to edit.2 In the Options menu in the upper right corner of the Library window, chooseProperties and click Set Path in the Video Properties dialog box.160 Chapter 5 AutoCAD DXF filesFlash supports the AutoCAD DXF format in the release 10 version.DXF files do not support the standard system fonts.Flash tries to mapfonts appropriately, but the results can be unpredictable, particularly for thealignment of text.Since the DXF format does not support solid fills, filled areas are exported asoutlines only.For this reason, the DXF format is most appropriate for linedrawings, such as floor plans and maps.You can import two-dimensional DXF files into Flash.Flash does not supportthree-dimensional DXF files.Although Flash doesn t support scaling in a DXF file, all imported DXF filesproduce 12-by-12-inch movies that you can scale with Modify > Transform >Scale.Also, Flash supports only ASCII DXF files.If your DXF files are binary, youmust convert them to ASCII before importing them into Flash.Converting bitmaps to vector graphicsThe Trace Bitmap command converts a bitmap into a vector graphic witheditable, discrete areas of color.Use this command to manipulate the image as avector graphic, or to reduce file size.If you convert a bitmap to a vector graphic, the vector graphic is no longer linkedto the bitmap symbol in the Library window.Note: If the imported bitmap contains complex shapes and many colors, the convertedvector graphic can have a larger file size than the original bitmap.Try a variety of settings inthe Trace Bitmap dialog box to find a balance between file size and image quality.You can also break apart a bitmap to modify the image using Flash drawing andpainting tools or to paint with the bitmap as a fill.See  Breaking apart a bitmapon page 163.Using Imported Artwork 161 To convert a bitmap to a vector graphic:1 Select a bitmap in the current scene.2 Choose Modify > Trace Bitmap.3 Enter a Color Threshold value between 1 and 500.When two pixels are compared, if the difference in the RGB color values is lessthan the color threshold, the two pixels are considered the same color.As youincrease the threshold value, you decrease the number of colors.4 For Minimum Area, enter a value between 1 and 1000 to set the number ofsurrounding pixels to consider when assigning a color to a pixel.5 For Curve Fit, select an option from the pop-up menu to determine howsmoothly outlines are drawn.6 For Corner Threshold, select an option from the pop-up menu to determinewhether sharp edges are retained or smoothed out.To create a vector graphic that looks most like the original bitmap, enter thefollowing values:" Color Threshold: 10" Minimum Area: 1 pixel" Curve Fit: Pixels" Corner Threshold: Many CornersThe results of using the Trace Bitmap command162 Chapter 5 Breaking apart a bitmapBreaking apart a bitmap separates the pixels in the image into discrete areas thatcan be selected and modified separately.When you break apart a bitmap, you canmodify the bitmap with the Flash drawing and painting tools.You can also paintwith the bitmap as a fill.Using the Lasso tool with the Magic Wand modifier, you can change the fill ofselected areas of a bitmap that has been broken apart.After you paint an area with a bitmap, you can use the Paint Bucket tool to rotate,skew, or scale the bitmap image.See  Using the Paint Bucket tool on page 142.To break apart a bitmap:1 Select a bitmap in the current scene.2 Choose Modify > Break Apart.To paint with a bitmap s image:1 Break apart the bitmap, as described above.2 Select the Eyedropper tool and then click the bitmap.The Eyedropper tool sets the bitmap to be the current fill and changes theactive tool to the Paint Bucket.3 Paint with the Brush or Paint Bucket tool.To change the fill of selected areas of a broken-apart bitmap:1 Select a broken-apart bitmap in the scene.2 Select the Lasso tool and click the Magic Wand modifier.3 Click the Magic Wand Settings modifier and set the following options:" For Threshold, enter a value between 1 and 200 to define how closely the colorof adjacent pixels must match to be included in the selection.A higher numberincludes a broader range of colors.If you enter 0, only pixels of the exact samecolor as the first pixel you click are selected." For Smoothing, select an option from the pop-up menu to define how muchthe edges of the bitmap will be smoothed.4 Click the bitmap to select an area.Continue clicking to add to the selection.5 Select a fill that you want to use to fill the selected areas in the bitmap.See Specifying stroke and fill attributes on page 136.6 Select the Paint Bucket tool and click anywhere on the selected areas to addthe new fill.Using Imported Artwork 163 Editing bitmapsIf you have Fireworks 3 or later or another image-editing application installed onyour system, you can launch the application from within Flash to edit animported bitmap.If you are editing a Fireworks PNG file imported as a flattened image, you canchoose to edit the PNG source file for the bitmap, when available [ Pobierz całość w formacie PDF ]
